I am building a large pond approx. 20' L x 12' W depths ranging from 12" to 40" in Santa Rosa, CA. North of San Francisco. We have average tempratures ranging from 35 to 85 F and records of 20 to 110 F. I guess I have 2 questions. 1. Can I put tropicals like Pacu's and Oscars in the pond?
> 2. What are a few good sources for construction of this pond? I intended on using a pool liner from a high grade soft side pool its very strong material I originaly got it so that my large dogs could get in the pool.

> Thanks For any help you can provide

Like stillearnin said, you'll definitely need heaters in winter, you should probably be shopping for several 500 or 1000W heaters
